In a publication edited by Professor David Jenkins, 'Birds in Mid Deeside, 1970-2012', there is confirmation that Greylag have summered near Dinnet sporadically since 1970s. Nesting was recorded in 1982,, and now breeds there in small but increasing numbers. The numbers of birds near Dinnet usually decrease from June onwards with few present in August as birds disperse to feed elsewhere. "In 2011 , up to 199 fed at Cromar from May onwards".
